Three major problems appear to underlie the increase in world disorder: (1) a rapidly accelerated age of social evolutionary change and world development, (2) continuing, serious levels of social injustice, and (3) widespread moral decay. The new scientific efforts to understand the causes of these problems and to seek their solution should consider using the following seven basic assumptions and principles: (1) the distinctiveness and superiority of humans as a species, (2) the interdependence of humankind, (3) the need for internationalism and world government to supersede nationalism, (4) the need for universal participation at the local, national, and international levels of world government, (5) the need to consider both the wholeness and diversity of humankind, (6) social justice as the guiding principle of world government, and (7) the achievement of world religious unity as a spiritual contribution to the achievement of world social justice. World criminology uses an interdisciplinary approach to understand the whole of human-kind and to link science with human values. Its three major interests are comparative criminology and criminal justice systems, special problems, and the development of world models. 40 references.
